These studies comprise four papers on subjects connected with respiratory disease. 1. A review of recent work on pneumonia (eighteen pages) by Eastwood, which is primarily a survey of the question of serologic races among pneumococci. The problem of pneumococcus types is well outlined in this article. 2. A laboratory study (twenty-five pages) by Griffith of types of pneumococci obtained from cases of lobar pneumonia in man, mostly in the London area. The conclusion is reached that the American Types I, II and III are serologically distinct and occur in cases of lobar pneumonia in England in almost the same proportion as in the United States. 3. A discussion (thirty pages) by Eastwood of the significance of serologic differences among pneumococci, at the end of which the author expresses his belief that Neufeld's views about the significance of serologic differences among pneumococci ought not to be accepted as final. 4.
